SuperTech HM 5w30 vs Kirkland 5w30

Exactly. I don’t know many premium brands selling re-refined group 2 mixed with group 3 as their top tier synthetic choice. I can guarantee Warren, Wally, and Costco aren’t leaving a cent on the table. In fact the Supertech Euro costs more than Mobil 1 Full Synthetic 0W-40 because IMO they couldn’t meet the specs with those base oils.

That said many engines don’t require anything more. Important to know your engine and conditions.
It’s adequate at best. It is a suitable oil (depending application and conditions) at an OK price point with good availability.

This notion that it’s the end all and be all oil is ridiculous.

By "re-refined" are you referring to recycled, meaning the oil was in some other car's engine, drained during an oil change, and then put through a cleaning process and re-refined as new oil?

I bought 4 jugs of Kirkland earlier in the year, and more than happy to use it in my Civic. Cost was $15/5 quarts. I have plenty of money for boutique oils, but they would be a waste of money giving my use case.

Further, I chuckle a little by the haters here. For people running 5-7k changes, which I suspect is far and away the most popular interval around here, the Warren oils have a well proven positive history.
 
I have ran them both but now run Quaker State High Mileage Full Synthetic for a little bit more
 
I don’t honestly care. I picked up Valvoline Restore and Protect and PUP for the same or even less with rebates.

The big name brands could spend $1B in advertising for all I care, I’m still getting the “premium brand” for the same or better than the store brands with very little effort.


I’m sure marketing is offset when you make the base stocks - and get to select what’s cost effective for each batch …

I just last week drained Supertech Full Synthetic out of my daughter’s high mileage Hyundai and put in some NAPA FS.

I’m definitely not a hater of store brands. I just temper my expectations and understand it’s a budget offer.

I ran that Napa oil in my Sentra for many years. Napa had a sale, and I bought a case. That stupid car had a 2.8 quart sump capacity, so the case lasted a LONG time. The engine ran like a top.
 

I remember reading on this forum, many years ago, a comment by a member directed at someone running Amsoil with a low mileage change interval. He said something to the effect that "the school buses in your town, running relcaimed oil, owe you a debt of gratitude, for providing such clean base stock for recycling". Ha ha. That one stuck with me...

Google AI suggests that Mobil 1 spent $100M on advertising last year. Kirkland & Supertech oil? Not much.
Kirkland is a very carefully curated brand that covers many, many products other than oil. Supertech, not so much, but the point is that Kirkland and Mobil 1 have very different marketing goals and go about it different ways. The second point is that Kirkland doesn't spend much promoting their oils, but the number is not zero, either. FWIW, I would only give the slightest edge to the basic Mobil 1 Syn over Kirkland, and for 5K OCI, assert their equivalence.

That’s good! I like that. When I was a kid used oil went on dirt roads to keep the dust down.
 
I’m not a hater of these oils, in fact I did run Supertech in my Civic for one 10k interval and I was actually planning on running Kirkland in it around that time as well. But then Valvoline Restore and Protect came out and I saw how much of an improvement it made in my consumption and it opened my eyes up a little bit more. I realized that even though the 2.0 in my Civic is easy on oil, I can’t just run the cheapest oil and expect it to keep the engine in perfect shape. I’m not saying that Supertech caused the consumption, in fact I think the initial “damage” was done by the original owner, who just went to the Honda dealer for most of the oil changes. So I feel like the best plan for this engine going forward, if I want it to get to 500,000 km, is to use the better quality oils that will do a better job of keeping the engine cleaner. I don’t think Supertech/Kirkland is good enough to keep engines perfectly clean in the long run

What "original damage? are you talking about?
 
I tried both oils and cars were burning it while they didn't with PP so I stopped using them.
Had to run an OCI with Valvoline Restore and Protect to stop oil burning in Sportage. Since then I run Pennzoil Platinum Euro LX or Mobil 1 ESP 0w-30 in both cars.
 
Ran Supertech in my Work Commuter Fiesta for years now, its done great with it, no complaints. Does that mean I'd run it in everything, no, but in the right application its a fantastic value. I figure the Transmission in the fiesta will most likely do it in before the engine does.

What "original damage? are you talking about?
Damage is a strong word (which is why I put parentheses around it). But I’m basically talking about how my Civic was burning a quart of oil every 6000 miles (which isn’t a big deal really) but after using Valvoline Restore and Protect it is using less than half that amount. So it’s a pretty significant improvement and so I feel like the rings must have a lot less carbon on them now.
 
It meets the same standards as raw oil does after being processed. If it is a group 3 it is the same as a group 3 that has came straight from the ground.
Yes it meets the same specs. I didn’t mean it was bad, just used for cost savings.
